Vodacom does not value their customers!!!

I reported my phone missing which was insured with vodacom and the lady at vodacom advised me to lodge a claim which they declined because they could not detect the vodacom sim card in it. The phone was later recovered and I reported it back to vodacom and they proceeded to do a sim swap for me. Unfortunately the phone fell and cracked screen so I had to take it in for repairs. Now vodacom is saying that they can't fix it because it's blacklisted. I explained that after finding the phone I did go back and report it to them and they even assisted me with a sim swap but the consultant does not want to hear it. They've continued taking my money (R300 per month) for insurance but refuse to do their part.. this is poor treatment of customers at its worst. I've been with them for a long time and never missed one payment and this is how they treat me, I will definitely not be renewing my contract which ends January 2024.
